- 101 Claims.

This invention relates to machines for shaping uppers over lasts and is herein shown as embodied in a machine having means for lasting the forepart and shank portions of shoes and adapted for operating upon shoes the margins of the uppers of which in the lasting operation are secured to the insoles by cement. It is an object of the present invention to provide improved means for lasting these different portions of shoes in a single operation, and various important novel features of the invention are accordingly to be recognized in the combination of forepart and shank lasting means. It will be evident, however, that the invention in many of its aspects is not limited to such a combination, but includes various novel and useful features relating more particularly to end or side lasting means.

In the illustrated machine the forepart and shank lasting means are relatively adjustable in directions lengthwise of the shoe to accommodate shoes of different sizes and, in order that these means may operate in difierent relative positions to lay substantially all portions of the margin of the upper forwardly of the heel breast line inwardly over the insole regardless of the size of the shoe being operated upon, there is pro rided, in accordance With an important feature of the invention, a novel construction such that the distance along the sides of the shoe that the forepart lasting means extends in effective engagement with the upper is also variable. In the construction shown the forepart lasting means comprises end wiper plates or wipers for operating at the extreme toe end of the shoe and side wiper plates or wipers for operating at the opposite sides of the forepart of the shoe beyond the end plates, the relation between the end plates and the side plates depending upon the abovementioned relative adjustment of the forepart and shank lasting means. More particularly, as illustrated, the side wiper plates are displaceable lengthwise of the shoe relatively to the end plates to vary the effective lengths of their acting faces in operating upon shoes of different sizes. and such displacement is controlled by the shank lasting means which is adjustab e lengthwise of the shoe relatively to the forepart lasting means. Since the shank lasting means, as herein illustrated, is arranged to act on the upper between the heel breast line and the ball line at opposite sides of the shoe, the forepart lasting or wiping means, which may also be termed end lasting or wiping means, embraces the entire forepart of the shoe being operated upon and, in the overlaying operation, acts to lay all portions of the margin of the upper forwardly of those portions acted upon by the shank lasting means inwardly over the insole. It is to be understood that in the novel construction thus provided for accommodating lasting means to shoes of difierent lengths, the invention is not limited to means that operates on the particular portions of a shoe above mentioned.

Preferably, in accordance with a further feature of the invention, the forepart lasting mechanism is constructed and arranged to locate shoes of difierent sizes lengthwise in the machine by engagement with their end faces, and is provided for this purpose with a toe end embracing band initially adjustable in directions lengthwise of the shoe relatively to the end embracing wipers and arranged for engagement with the toe end of the shoe to determine its lengthwise position in the machine. The shoe is supported for the operation of the machine by toe and heel rests which are arranged to permit the shoe to be moved lengthwise in the machine into engagement with the toe band, these rests being relatively adjustable in directions heightwise of the shoe to position the shoe with the bottom face of its forepart in a predetermined plane.

For positioning the shoe heightwise in operative relation to the end embracing wipers the machine herein shown is provided with a holddown arranged for engagement with the insole to depress the shoe to the proper level for the operation of the wipers; and in order to assist in shaping the upper to the contour of the last prior to the overwiping operation; there are further provided, in accordance with a feature of the invention, grippers mounted above the wipers in position to grip the margin of the upper around the end and at opposite sides of the end portion of the shoe, the grippers being arranged during the depression of the shoe to pull the upper over the last and to draw it tightly over the forepart of the last. The wipers and grippers, in the construction shown, are fixed against relative heightwise movement and, in order that the upper will be properly tensioned over the forepart of the last, the grippers are arranged radially about the end or" the last to maintain the direction of pull substantially normal to the edge curvature of the last. The grippers are movable toward and from the shoe in a plane substantially parallel with the wipers and are held initially against inward movement toward the shoe by means which is arranged to yield in response to the pull of the upper to permit the grippers. to move farther inwardly and thus to assist in drawing the upper close to the lateral faces of the forepart of the last.

For conforming the upper tightly and smoothly to the contour of the shank portion of the last and insole the invention further provides novel shank lasting means, the machine illustrated having opposite shank lasting mechanisms comprising wipers of yieldable material shaped to conform substantially to the longitudinal curvatures of the opposite side edges of the insole both heightwise and laterally of the shoe and arranged to act on the upper between the heel breast line and the ball line at opposite sides of the shoe. The wipers are arranged to engage the upper initially in locations at considerable distances below the bottom face of the insole, and 'means is provided for holding them yieldingly in engagement with the opposite sides of the shoe to cause them during the depression of the shoe, by frictional contact with the upper, to work it toward the bottom face of the insole, the wipers being thereafter movable to lay the margins of the upwipedportions of the upper inwardly over the insole. In order to eliminate any excessive-forward strain on the upper by the grippers as the upper is wiped upwardly and inwardly over the curved surfaces of the shank portion of the last there is provided, as herein illustrated, connections between the grippers at the opposite sides of the forepart of the shoe and the shank lasting wipers arranged to cause saidgrippers to partake of the inward movementsof the wipers. This not only tends to prevent the'formation of wrinkles in the shoe upper at=the forward endsof the shank lasting wipers, but assistsin drawing the upperclose to the sides of the forepart of the last, particularly at the ball line.

The above and other features of the invention, including a novel construction and arrangement of wiper operatingand controlling means, novel shoe supporting means, and various novel detailsof construction and combinations of parts willnow be more particularly set forth by reference-tothe accompanying drawings and pointed out in the claims.

The illustrated machine is provided with mechanism for lasting the forepart of the shoe and with mechanism for lasting the shank portion of the shoe, which mechanisms are operated and controlled by cams on a cam shaft 28 mounted in suitable bearings in the frame 22 of the machine and which carries a spiral gear 26, Figs. 1, 2 and 8, driven by a worm 26 on a laterally extending shaft 28. Mounted on the shaft 28 is a clutch member 30 connected to the shaft by means of a spider .32 the opposed arms 36 of which slidably engage the cutch member 30 in grooves 36 in the clutch member to permit the latter .to 'be moved lengthwise of the shaft into engagement with a brake surface 38 on one side or into engagement with a driving member 40 on the other side. The driving member 49 is pinned to ashort shaft 42, Fig. 8, mounted in the frame 22 in axial alinement with the shaft 28, the shaft Q2 and the member 49 being driven continuously by means of a'belt is (Fig. 1) which engages a pulley '46 fast on the right-hand end of the shaft 62. A spring 38, which bears at one end against acollar fiflpinned to the shaft 28 and at the other end against a sleeve 52 threaded on the reduced end portion of the hub 55 of the member 30, tends to throw the member 39 into driving relation to the member iflbut is compressed by the rocking of a lever 56 in a clockwise direction, as viewed in Fig. 8, to move the clutch member 39 into engagement with the brake surface 38 when the machine is to be stopped.

The lever 56 is pinned to a rock shaft 58 mounted in the frame 22 and, as shown (Figs. 2 and 7)., is bifurcated to straddle the hub 54 and is provided with openings through which extend pins 60 which enter corresponding openings in.

a collar 62 mounted on the hub 54 between the sleeve 52 and a shoulder 64. For rocking the lever .55 in a clockwise direction to stop the ma chine there-are provided three stop earns 66, 68, and carried by a cam disk 12 (Fig. 1) on the cam shaft 20. A cam lever 14 fulcrumed at 16 to the frame carries at its upper end a roll 18 which is held in engagement with the cam disk I2 by a spring 8!] one end of which is connected at 82 to the frame and the other end of which is connected at 84 to the cam lever M. The cam lever M is connected by a link 86 to an upwardly extending arm 88 fast to a rock shaft 96 mounted in the frame 22 in parallel relation to the rock shaft 58 and to which there is secured a second arm .92, Figs. 1 and 8, having a plate 94 thereon arranged to engage a plate 95 on a laterally extending arm 98 pivotally connected to the upper end of an upwardly extending arm H19 fast to the rock shaft 58. A spring I92 connecting the arms 82 and 98 tends to hold them in the positions shown in Figs. 1 and 8 with a depending lug I84 on the plate 95 extending below the upper surface of the plate 95. It will be seen that, as the cam lever id is swung in a clockwise direction by one or the other of the stop cams, the arm 92 wil be swung in the same direction and through the arms 38 and Its clockwise movement will be imparted to the lever 56 to move the clutch member 33, against the pressure of the spring 48, into engagement with the brake surface 38 to stop the machine.

To start the machine the arm 98 is swung upwardly by depression of a treadle I06 (Fig. 2) to disengage the plates 34, 96 and thus to permit the spring G8 to move the clutch member 30 into engagement with the driving member 59. The treadle I95 is fulcruined at Hi8 to the frame 22 and is connected by a rod Ilii to an arm I I2 fast to a shaft H4 which is mounted in the frame 22 and to which there secured a second arm IIB (Fig. 8). Pivotally connected to the outer end of the arm I I8 is a downwardly extending member I i8 having a hook-shaped lower end I29 arranged to engage a pin I22 projecting from the arm 83. A spring I2i connected at one end to a pin I25 in the hub of the arm Hi and at the other end to a pin i255 carried by the member H8 tends to hold the end I20 of the member H8 in engagement with the pin I22. When the arm 98 is swung upwardy by depression of the treadle an abutment 38 on the arm Hi3 engages an adjustable stop illustrated as a screw I 32 carried by the member H8. In the continued depression of the treadle, the arm H8 is accordingly swung by the arm I it far enough to disengage its hookshaped end I29 from the pin thus permitting the spring I62 to swing the arm 88 downwardly to move the plate 95 into operative relation to the platet i in order that the machine may be stopped automatically even if the operator continues to hold the treadle depressed. As shown particularly in Fig. 2, the treadle I536 is provided with a pair of opposed stops ilustrated as screws set. are which are arranged to engage the frame 22 and which may be adjusted to vary the extent of swinging movement imparted to the treadle Hi6 and the arm H6, and one of which, I34, may be adjusted to vary the initial positions of these parts. The treadle is held normally in raised position, with the stop i3=l in engagement with the frame 22, by a spring I38 one end of which is connected at I iii to the frame 22 and the other end of which is connected at M2 to the treadle IE5. As illustrated, and for purposes to be explained more particularly hereinafter, the three stop cams on the cam disk '52 are so disposed that the machine is stopped automatically at certain predetermined points in its cycle of operations.

The last with its shoe upper and insole assembled thereon is supported for the operation of the machine by a toe rest I44 and a member M6 which may be conveniently termed a heel rest although it engages the top of the cone of the last somewhat forwardly of the heel end, Figs. 1 and 4. The upper surface of the toe rest I44 is curved to conform substantially to the shape of the top of the toe end of the last and may be covered with leather or other suitable material to prevent marking of the shoe upper. In the illustrated machine the toe and heel rests are mounted for movements in directions heightwise of the shoe and are upheld when the machine is idle by a comparatively light compression spring which acts on both rests as part of an equalizing device through which the two rests are subjected to equal pressures by the spring while permitted to move relatively to each other to adjust themselves to the shoe. As shown, the toe rest is adjustably secured to the upper end of a rod I48 5 which extends downwardly through a bearing I50 inthe frame 22 and has slidably mounted on its lower end portion a block I52. Pinned to the end of the rod I48 and engaging the block I52 is a collar I54, and clamped to the rod, one on each side of the bearing I56, are adjustable collars I55, I58. Surrounding the rod I48 between the collar I56 and the block I52 is a stiff compression spring I60. The heel rest 36 is slidably mounted for movement lengthwise of the shoe in ways I62 formed in a member E64 pinned to the upper end of a rod I56 which extends downwardly in a central bore (Figs. 1 and 9) in a bushing I 68 slidably mounted in the frame 22 in parallel relation to the rod I48. Surrounding the rod I66 between the bushing I68 and the member I64 is a stiff compression spring I69, the capacity of which is substantially the same as that of the spring I60. Formed integral with the bushing I88 is a rod I'Ifi which is surrounded by a sleeve I72 bored for nearly its entire length to receive the rod, the rod being provided with a reduced end portion I14 which extends through an opening in the lower end of the sleeve and has pinned to its lower end a collar I16. Surrounding the reduced end portion I M of the rod I10 and bearing at one end against a shoulder on the rod and at the other end against a shoulder on the sleeve is a comparatively light compression spring I82. The sleeve H2 is provided with trunnions I84 to which there are pivotally connected, one on each side of the sleeve, equalizing levers I92 the opposite ends of which are pivotally connected to trunnions I94 formed on the block I52 on the rod I48. Intermediate their ends, the levers I92 are pivoted at I93 to the upper end of a link I 96 in the lower end of which there is formed a slot I 98 to receive a pin 2G0 carried by an arm 2B2 pinned to a rock shaft 204 mounted in the frame 22. The equalizing levers I92 are supported by a link I38 which is pivoted at E93 to the bifurcated upper end of the link 5% and has formed in its upper end a slot I88 through which extends a pin I99 carried by the frame of the machine. When the machine is initially at rest the pin 1% is arranged to engage the link I 85 at the upper end of the slot I88 and, with the pin in this position in the slot, the link I96 is upheld with the pin 2% engaging it at the lower end of the slot I538. Fast to the rock shaft 5 264 is a lever 206 having a forwardly extending arm 208 carrying a cam roll 2 I9 arranged to engage a power cam 2I2 on the cam shaft 29. A spring 2 I4 connected at end to the frame 22 and at the other end to a second arm 246 with which the lever 286 is provided tends to hold the cam roll ZIfl in engagement with the cam 2I2. From theabove description it will be readily seen that the spring I82 acts through rod .Illl and spring I59 to uphold the heel rest I46, and through the sleeve H2, equalizing levers I22 and spring 560 to uphold the toe rest 9%, and that through the swinging of the levers Iii? about their pivot I93 equal, but opposite, movements of the toe and heel rests Hit, I46 in directions heightwise T0 of the shoe are permitted so that the rests will adjust themselves to the shoe when the work is presented to the machine. By adjustment of the toe rest his relatively to the rod I48, permitted by a split bearing at the upper end of the rod, i5

the heightwisepositionszof the rests I44, I46 may be varied :to support the shoe and last in the desired heightwise positionin the machine.

For locking the sleeve I72 to the rod l70-at a predetermined time in the cycle, for a purpose hereinafter more fully described, there is provided a pawl 2 I8 pivoted at 220 to the sleeve I72 and arranged to engage ratchet teeth 222 formed on the rod I70. The pawl 2I;8 has an arm 224, and pivotally connected to the outer end of the arm is a rod 226 which extends downwardly through the arm 202 and the pin 200. Surrounding the rod 226, one on each side of the arm 202, are equalizing springs 230 one of which bears against the upper side of the arm and a shoulder 232 on the rod and the other one of which bears against the under side of the arm and a nut 234 threaded on the end of the rod. The springs'230 tend to hold the pawl 2 I8 in any position into "which it may be moved by the arm 202 which is so positioned when the machine is initially at rest that the pawl is held out of engagement with the ratchet teeth 222 to permit the 'toe and heel rests I44, I46 to be upheld by the spring I82.

In the course of the operation of the machine, as hereinafter more fully explained, the shoe is depressedJoy pressure applied to its bottom face, against the resistance of the spring I82 which is compressed by the downward movement of the rests I44, I46 through the opposite movements of the rod 170 and the sleeve I72, the spring acting with equal forces on both the rests. During the depression of the shoe, the springs I66, I69, which as previously pointed out are considerably heavier than the spring I82, remain fully expanded and act substantially as solid members. At a predetermined time'in the cycle of the shaft 20 and preferably, aspointed out more particularly hereinafter, at the time when themargin of the upper is being laid inwardly over the insole, the arm 202 is swung upwardly, by the action of the cam 2I2 on the lever 206, and acts through the spring 230 to swing the pawl 2I8 into engagement with one of the ratchet teeth 222 on the rod I70, thereby locking the sleeve I72 to the rod I70 and throwing the spring I82 out of operation, i. e., preventing further compression of the spring. As the cam 2I2 continues to swing the arm 202 upwardly the pin 200 engages the link I96 at the upper end of the slot I98, after which the levers I92 are moved upwardly through the link I96 to compress the springs I60, Hi9 and thus to increase the pressure of the overlaying means on the margin of the shoe upper. It will be seen that the link I86 moves relatively to the pin I90 as the levers I92 are moved upwardly and that since the levers I92 are held against swinging movement by reason of the locking of the sleeve I72 to the rod I70, the springs I60, I 69 are compressed equal amounts. The configuration of the cam 2I2 is'such that when it is desired to return the parts to their starting positions, the springs I60, I69 are permitted to expand fully, after which the spring 2 I4 acts to swing the arm 202 downwardly to unlock the sleeve I72 and the rod I70 and through the engagement of the pin 26!) with the link I96 at the lower end of the slot I98 to move the levers I92 and the link I86 downwardly until the pin I90 engages the link I86 at the upper end of the slot I88.

The forepart lasting mechanism, later to be described in detail, and comprising grippers 236, 237 (Fig. 3) for engaging the upper at the toe end and at opposite sides of the forepart, wipers 288 for laying the upper in overthe edge of the shoe bottom around the toe end and along the opposite sides of the forepart of the shoe, and a toe end embracing band 240, is mounted above the frame 22 in a carrier 242 (Fig. 1). The carrier 242 is pivotally connected near its front end to the upper ends of a pair of links 244 (Figs. 1 and 2) fast to a laterally extending shaft 246 mounted in theframe 22. At its outer end the carrier is pivotally supported on the upper end of a lever 248 which is fulcrumed at 250 to the frame and has a downwardly extending arm 252 carrying a roll 254 en gaged by a path cam 256 formed in one side of a cam wheel 258 on the shaft 20.

For lasting the sides of the shank portion of the shoe there are provided opposite shank lasting mechanisms, Figs. 2 and 3, each of which comprises a lasting device 260 secured to a carrier 262 which is mounted for movements toward and from the shoe in ways 264 formed in a member 266 slidably mounted for movements lengthwise of the shoe on a support 268 secured to the frame 22, Fig. 4. Each lasting device comprises a molded member or wiper 270 of yielding frictional material, for example, rubber, and a holder 272 having a downwardly inclined portion 274 for supporting the member 276 and a shank portion 276 extending into a slot 278 in the carrier 262. The members or wipers 270 are shaped to conform substantially to the curvatures of the edge of the last bottom, or the edge of an insole on the last, both heightwise and laterally of the last and as shown are of sufficient lengths to engage the opposite sides of the shoe from points substantially at or somewhat to the rear of the heel 3 breast line forwardly to the ball line. Each lasting device is removably secured to its carrier by a pin 280 so that it may be replaced by a lasting device of different shape for lasting a shoe of different style. For positioning the lasting devices in proper relation to the sides of the shoe mounted upon the toe and heel rests I44, I46, there is provided in the illustrated machine manual means for imparting to the members 266 adjusting movements in the same direction lengthwise of the shoe. Each member 266 has threaded therein a rod 282 the outer end portion of which is rotatably mounted in a bracket 284 secured to the frame 22. Mounted in the brackets 284 and secured to the rods 282 are equal pinions 286 the teeth of which mesh with teeth formed upon a rack bar 288 (Fig. 5). The rack bar 288 is slidably mounted in ways formed in cover plates 290 on the brackets 284. Fast to the outer end of one of the rods 282 is a hand wheel 292 for rotating that rod, the construction being such that as that rod is rotated by the hand wheel, the other rod, through the pinions 286 and the rack bar 288, is rotated in the same direction so that both the lasting devices are adjusted in unison.

The carrier 262 of the front shank lasting mechanism has pivotally connected to its outer end a link 294 through the outer end of which extends a pin 296 carried by the spaced upwardly extending arms of a forked lever 298 fast to a rock shaft 300 mounted in the frame 22. Pinned to the rock shaft 300 is a rearwardly extending arm 302 which is connected by a short link 804 to the upper end of a rod 306 (Figs. 1 and 14) which extends downwardly through a block 308 pivotally supported on the outer end of an arm 3I0 fast to a rock shaft 3I4- mounted in suitable bearings in the frame 22., Surrounding the rod 306 between the block 308 and a collar 3 I6 pinned to the lower end of the rod is a compression spring 3I8. The carrier 262 of the rear shank lasting mechanism is connected to the rock-shaft 3 [4 by mechanism which is substantially the same as that described above for connecting the carrier 262 of the front shank lasting mechanism to the rock shaft, the shaft 330, however, of the rear mechanism being formed in two parts to prevent interference with other parts of the machine and the two parts of the shaft being geared together by equal pinions 323, Fig. 3, through a short intermediate shaft 322 mounted in the frame 22. The opposite shank lasting devices 263 are held in engagement with each other by the springs 3l8 when the machine is at rest prior to the beginning of its cycle. These devices are accordingly displaced by the operator as he mounts a shoe on the toe and heel rests I34, I43 which are so positioned at this time that the devices 230 in their displaced positions engage the opposite sides of the shoe a considerable distance below the edge of the shoe bottom (Fig. 13). Pinned to the rock shaft 3M is an arm 325 (Figs. 1 and 11) provided with an arcuate slot 328 through which extends the shank portion of a colt 333. To this bolt there is pivotally connected the upper end of a link 332 the lower end of which is pivotally connected at 335 to the upwardly extending arm 334 of a lever 336 fulcrumed on a shaft 333 in the frame 22. The lever 333 has a downwardly extending arm 3 1i] carrying a roll 332 engaged by a path-cam 334 formed in one side of a cam wheel 335 on the shaft 23. In order to adjust the initial tension of the springs 35? the link 332 is formed in two parts, the oppositely threaded end portions of which are connected by a turn buckle 338 which is held in adjusted position on the two parts of the iink by lock nuts 353. When the machine is initially at rest the arcuate slot 328 formed in the arm 323 is concentric with the pivot 335 of the link 332. It will be seen that by adjusting the position of the bolt 333 in the slot 328 the efiective length of the arm 326 may be varied to impart more or less turning movement to the rock-shaft 313 by the action of the cam 33 3 on the lever 335 to compress the springs 3l8.

After the opposite shank lasting devices 260 have been adjusted lengthwise of the shoe to position them properly relatively to the shank portion of the shoe, the margin of the upper around the toe end and at opposite sides of the forepart of the shoe is gripped by the grippers 233, 23'! of the forepart lasting mechanism. The operator then swings a holddown 352 with which the machine is provided into position over the shoe bottom. The holddown 352 is carried by an arm 353 which is pinned to the upper end of a shaft 358. The shaft 356 is rotatably mounted in the frame 22 and the arm 353 is provided with a handle 358 by means of which it may be swung by the operator to move the holddown into and out of operative position over the shoe bottom. As shown, particularly in Fig. 4;, the holddown 352 is formed in two parts comprising a forward arm 353 to the lower end of which there is secured a plate 333 for engaging the toe end of the insole, the plate 380 having an edge contour similar to the contour of the toe end portion of the insole to hold it in proper relation to the bottom of the last, and a rear arm 355 for engaging the insole at the heel end. In order to accommodate shoes of different lengths the arms 353, 355 of the holddown are adjustable in directions lengthwise of the shoe. As shown, the arms are provided at their upper ends with tongues 351 (Fig. 13) slidably mounted in a groove 359 formed in the end portion 36f of the'arm 354. The end portion 36! is slotted lengthwise above the groove 359, the two parts of the slotted portion being connected by clamp screws 363 by 5 means of which they may be moved toward each other to clamp the arms 353, 355 in any positions of adjustment into which they may be moved. The shaft 353 is supported by a block 332 (Fig. 2) which surrounds a reduced end portion 364 of the shaft between a shoulder 366 formed on the shaft and a collar 368 pinned to the shaft. Formed on the block 362 are trunnions 310 to which are pivotaliy connected links 3l2 held in position thereon by cap screws 313, and the links 15 are connected at their lower ends to the outer end of one arm 333 of a bell-crank lever 33'! (Fig. 10) which is fulcrumed on the shaft 338 and is provided with a downwardly extending arm 318 carrying a roll 383 engaged by a path cam 382 formed in one side of a cam wheel 3% on the shaft 23. The configuration of the cam 332 is such that at a predetermined time in the cycle of the shaft 23 the arm 318 is swung in a direction to lower the shaft 353 to move the holddown 25 into engagement with the insole and then to depress the shoe and the rests I44, I46 relatively to the grippers 236, 237 and the shank lasting devices 233 against the resistance of the spring E32 as 'hereinbefore described. As the shoe is depressed, the grippers 233, 231 pull the upper forwardly on the last and draw it tightly over the forepart of the last. At the same time the shank lasting devices 260 act to upwipe the upper along the sides of the shoe to conform it to the shank portion of the last. The illustrated machine is provided with means arranged to engage the shank portion of the insole and to hold its opposite marginal portions yieldingly against the bottom of the last until the shank lasting 40 wipers have begun to lay the marginal portions of the upper over the insole, comprising shank holddown members 365 which are curved both laterally and heightwise of the shoe to conform substantially to the curvatures of the opposite edges of the insole. Each member 365, Figs. 4, 13 and 14, is pivotally connected at 36"! to a lug 369 on a slide 3' mounted for movement in directions heightwise of the shoe in a guideway formed by the opposite edge portions of a pair of plates 373 secured to a member 315 slidably mounted for movements in directions laterally of the shoe in a guideway 311 formed in the forwardly projecting portion 379 of the rear arm 355 of the holddown 352. I a tongue 38! in the guideway 31?, the tongue being provided with a pair of recesses 383 either one of which is arranged to'be engaged by a spring-pressed plunger 335 carried by the forward portion 353 to determine the position of the members 335 laterally of the machine in operating upon right and left shoes. The member 3715 is provided at its lower end with a bore for supporting a pair of spring-pressed plungers 331 which surround the opposite end portions of a spring 389 and which engage spherical seats 39l formed in the members 365 and urge them outwardly. Tail portions 393, with which the members 335 are provided, limit their outward movements by engagement with adjustable screws I The member 315 has 55 to grip the margin of the shoe upper.

insole engaging edges to accommodate shoes of different widths.

Each slide 3H has a projecting lug 40I carrying a pin 403 arranged to center a spring 405 the upper end of which surrounds a pin 40! carried by the member 315. The springs 405 tend to hold the slides 3' with the lugs 40I in en: gagement with stops 409 on the plates 313. The position of the stops 409 heightwise ofthe machine is such, however, that as the holddown 352 is moved downwardly the members 335 engage the opposite edge portions of the shank of the insole before the plate 360 and the rear arm 355 move into engagement with the toe and heel end portions of the insole, the springs 405 yielding to permit this relative movement. The members 365 are thus moved into positions to press the opposite margins of the shank portion of the insole yieldingly against the bottom of the last during the depression of the shoe and until after the wipers 210 have begun their movements inwardly over the insole to lay the margin ofthe upper against the insole. As shown, the members 365 are provided with slightly concaved upper-engaging faces 4 which, as the wipers 210 move inwardly, act to bend the margins of the upper around the curved forward edges of the wipers. As the wipers continue their inward movements the margins of the upper are thus clamped against the wipers by the members 365 which, as they are swung inwardly about their pivots 361 in response to the pressure of the wipers thereon, act tohold successive portions of the margin of the upper out of engagement with the insole until each successive portion is pressed against the insole by the advancing Wipers.

As shown, particularly in Figs. 3 and 4, the carrier 242 for the forepart-lasting mechanism is provided with a cover plate 3 86'upon the upper surface of which there are mounted a plurality of blocks 388 provided with guideways- 390 in which are slidably mounted the grippers 236, 23? for engaging the shoe upper around the toe end and at opposite sides of the f'orepart. In order that the shoe engaging surfaces of each gripper will be maintained substantially parallel to' the portion of the upper to be seized the blocks 383 are disposed in directions substantially normal to the edge curvature of the shoe bottom. Since the grippers 230, 231 are identical-in construction, a description of one Will. sufilce for all. Each gripper comprises a jaw 392 formed upon the forward end of a slide 394 and a gripper jaw 336- pivoted to the forward end of the slide 394 and provided with a tail 398 by means of which it may be swung about its pivot toward the jaw 332 This is accomplished in the illustrated machine by a lever 400 pivoted at 402 to the slide 394, which lever is provided with a nose portion 484 underlying the tail 398 of the gripper jaw 395-. The lever 400 has an arm 406 to which there is pivotally connected at 4l5 a handle 498 having an upwardly extending portion arranged to be grasped by the hand of the operator. The handle 408 has an overhanging portion 4) which, as the handle is swung downwardly, engages the upper surface of the arm 406- and swings it in a directionto elevate the nose portion 404-, which by engagement with the tail 398 causes the gripper jaw 396 to swing toward the gripper jaw 392 to grip the shoe upper. In its elevated position (Fig. 16) the nose portion 404 of the lever 400 is at right angles to the 398 so that the gripper jaws 392; 396 are'locked in upper gripping position. As the handle. 408 is swung re.- versely a pin 41-2 carried by the handle enters a notch- 444- in the arm 406 and swings the arm upwardly to lower the nose 404 and thus to per- 5 mit a spring 4|6, which is connected to the tail 398- and the slide 394-, to swing the jaw 396=away from the jaw 392- to release the shoe upper. Each slide 394 is held initially in retracted position in its guideway 390 with the gripper jaw 392 in engagement with the end of the cover plate 386 by aspringv 45 8 which is connected at one. end to a pin 420 carried by the slide and at the other end toa pin 422 projecting from. the cover plate The toe-end embracing. band 240 of the forepart lasting mechanismasshown particularly in Figs. 4, 6, and 7A, comprises a U-shaped strip of leather or other suitable material carried by supports or holders 424 located at. the corners and 20.1

at the opposite sides of the band and a support 428'for the front 'endof the band. 'I'hesupports 424 are slidably mounted in holders 428' (Fig. 7) which are provided'witharc-shaped'ribs 430 guided in corresponding recesses formed in. a plate 432, 25. i

so that the holders are mounted for swinging. movements about an axis located substantially at the toe end of the shoe. The plate 432 is mounted-for movements in directions lengthwise of the shoe in ways formed in. the carrier 242.

The supports 424, as shown particularly in Fig. 7A are mounted in slots 434 in the holders 428 and are provided with recesses for receiving springs 436which bear at'their outer ends againstthe holders 428 at the ends of the slots 434 and thus tend to urge thesupports 424 inwardly with the heads of stopscrews 438 carried by the holders 424 in engagement with the holders 428 at the forward ends of slots 440 formed in the holders in alinement with the slots 434'. The support 426 40; for'thefront end of the band is slidably mounted in the plate 432 and has an outwardly extending rod. 442 which projects through a bushing, 444 threaded into the plate 432. Surrounding the rod 442 between the inner end of the bushing and the end of the support 426 is a spring 446 the initial tension of which may be varied by adjust- 'ment of the bushing. Threaded on the endof the rod 442 isai knurled nut 448 which is held in engagement with theouter endofthe bushing to 444 by the spring 443 and which may be turned to move the support 426 toward or from-the shoe to vary theposition of the front-end of the band lengthwise of the shoe relatively to the wipers the band 249 slipping in the holders 424 as it is adjusted relatively to the wipers. When the shoe is presented to the machine the toe band 240 is in itsopen position and acts as a stop or gage for positioning the shoe lengthwise in the machine.

For closing the toe band 240 about the toe end of the shoe as it isforced more firmly against the end of the toe by the movement of the plate 432 thereare pivotally mounted on the plate 432 gears 450 the teeth of which engage teeth formed on the edges of the holders 428 and also teeth formed on rack bars 452 slidably mounted in ways formed. in the carrier 242. At its outer end each rackbar 452 (Fig. l) carries a pin 434 the opposite end portions of which enter lengthwise slots 456 formed. in the forked upper end of a lever 458-fulcrumed at 460 to the frame 22. Each lever 458- has oppositely extending lugs. 462' carrying screws 464 which engage the frame 22 and by means of which the lever 458 may be swung about its pivot to adjust the toe band 240 to accommodate shoes of diiierent sizes. From the above description it will be evident that inward swinging movements will be imparted to the holders 528 to close the toe band about the end of the shoe in response to lengthwise movement or" the plate 432 relatively to the rack bars 552. For imparting to the plate 532 its lengthwise movement to close the toe band in proper time relation to other operations there is provided a path cam 555 (Fig. 11) formed in one side of the cam wheel 356 on the shaft 25. The earn 465 is engaged by a roll 415 carried by the laterally extending arm 572 of a lever 414 fulcrumed on the shaft 535. The lever 474 is provided with an upwardly extending arm 4'15 to which thereis adjustably connected one end of a link 418 the opposite end of which is connected at 579 to one arm 5% of a bell-crank lever 452 fulcrumed on the shaft 355. The lever 582 has an upwardly extending arm 554 connected by a pin and slot connection 585 to the plate 532. In order that more or less closing movement may be imparted to the toe band to take care of variations in the shapes of diiierent toes, the link M8, as shown in Fig. 11, is pivotally connected to a bolt 5?! the shank portion of which extends through an arcuate slot 513 formed in the arm 515. When the machine is initially at rest the slot 473 is concentric with pivot 575 of the link 5'15. By adjusting the position of the bolt 4'?! in the slot 473 the effective length of the arm 575 may be varied to vary the extent of forward movement imparted to the plate 432.

The forepart wipers 233 are mounted in the carrier 242 on holders 488 which are mounted on a plate 595 for swinging movements about the same axis as the toe band holders 528. The wipers are shaped to conform substantially to the shape of the toe end of the shoe, and in order that all portions of the upper forwardly of the shank lasting devices 255 will be wiped in over the edge of the shoe bottom, the wipers comprise end members or plates 452 secured to the holders 588 and side members or plates 554 slidably mounted in the holders and positioned lengthwise of the shoe by the shank lasting devices Figs. 4 and 6. The side members 595 are provided with laterally extending lugs 555 through which extend rods 458 carried by the holders 558. Springs 555 surrounding the rods 555 between the lugs 495 and shoulders 552 formed on the holders act at all times to hold the side members with their forward ends in engagement with stops 554 carried by the opposite shank lasting devices. The side members 594 are thus always under the control of the shank lasting devices, so that whatever may be the adjusted positions of the latter the shoe is lasted all along the sides of the forepart and shank.

For imparting to the wipers their swinging or closing movements they are advanced lengthwise of the shoe by the carrier 252 the plate 495 has pivotally mounted thereon gears 555 the teeth of which mesh with teeth formed upon the edges of the holders 558 and also with teeth formed on rack bars 558 slidably mounted on the plate @953. The rack bars 558 extend outwardly through the rear end of the carrier 252 and have pivotally connected totheir outer ends adjustable rods 5i5 (Figs. 1 and 12) threaded through blocks 5H2 which are pivotally connected to the upper ends of arms 515 of levers 5l5 fulcrumed at M8 to the frame 22. Each lever 5l5 has a downwardly extending arm 52!! which is arranged to be engaged by an adjustable stop illustrated as a screw 522 carried by a member 525 adjustably secured to the upwardly extending arm of the previously-mentioned lever 248. As shown, the member 524 is secured to the arm by bolts 525, the shank portions of which extend through lengthwise slots 52? formed in the arm.

Each arm 5E5 of the levers 5i5 carries an ad- J'ustable stop illustrated as a screw 55! which is threaded through a lug 553 (Figs. 1 and 12) in the arm and is arranged, when the parts are in the positions shown in Figs. 1 and 12, to engage a spring-pressed plunger 555 mounted in the from 22 of the machine. As shown each plunger 555 is provided with a reduced end portion 50? which extends through a bore 559 in the frame 22 and an enlarged portion 5 which is held against the frame 22 at the upper end of an enlarged portion 555 of the bore 559 by a. spring 5 i i the tension of which may be varied by adjustment of a screw 5i5 threaded into the lower end of the enlarged portion of the bore. As the lever 258 is swung about its pivot to move the carrier 252 toward the shoe the levers 5H3 move with the carrier, thereby moving the stops 55! away from the plungers 555 until the stops 522 engage the arms 525 of the levers 5i5. Thereafter as the lever 258 continues to swing in the same direction the stops 522 swing the levers 5l6 to move the rack bars in a direction opposite to the direction of movement of the carrier and thus to impart closing movement to the wipers. At the end of the forward movement of the carrier the levers 5 i5 will have been swung an amount suincient to close the wipers and to move the stops 55! again into engagement with the plungers 555. As the lever 255 is swung in the opposite direction to move the carrier away from the shoe the levers 555 and the rack bars 555 are held against movement with the carrier by engagement of the stops 55! with the plungers 505 so that the wipers are swung away from. each other during this movement of the carrier.

It will be understood that the stops 5% are adjustable to take care of variations in the extent of swinging movements imparted to the levers 5i 5 by reason of the adjustment of the stops 522 to vary the time in the forward movement of the carrier when the wipers begin their closing movements, or by reason of the adjustment of the member 525 tovary the extent of closing movements imparted to the wipers, and that in the normal operation of the machine the plungers 555 are intended to act substantially as solid members to hold the levers 5% against swinging movements as the carrier 252 is moved away from the shoe. In order, however, to prevent damage to the various parts of the wiper operating mechanism if the operator fails to adjust the stops 55i as may be necesssary by reason of the adjustment of the stops 522 or of the member 524, or of both, the tension of the springs 5 is such that they will yield to permit displacement of the plungers 555 if the wipers have been fully opened before the carrier has completed its movement away from the shoe, or if the stops 55! engage the plungers 555 before the levers 555 have completed their swinging movements to close the wipers in the movement of the carrier toward the shoe.

As shown in Figs. 1 and 3, the rods 5! 5 areheld in adjusted positions relatively to the blocks M2 by lock nuts 5E5 which are threaded on the rods and are arranged to engage the opposite end faces of the blocks. It will be seen that by adjustment of the rods 555 the initial positions of laterally of the shoe may be varied to insure that the margin of the up er for substantially its entire width will be wiped inwardly over the insole. From the above description, it will be readily seen that as the carrier is moved toward the shoe the end plates 432 both advance and close, while the side plates move only in directions laterally of the shoe, the springs 588 being compressed somewhat in the wiping operation. One advantage of this is that there is no tendency to displace unduly lengthwise of the shoe the portions of the margin of the upper along the sides of the forepart.

As previously stated, as the shoe is depressed by the holddown 352 the upper is pulled lengthwise of the last and drawn tightly up over the forepart by the grippers 233, 231 and it is also wiped upwardly around the toe end by the toe band 248 which is closed about the toe early in the downward movement of the holddown by the movement of the plate 432 toward the shoe. It will be understood also that as the shoe is depressed the upper along the sides of the shoe is up-wiped by the shank lasting devices 258 which are pressed yieldingly against the sides of the shoe through the springs 3 iii.

In order to eliminate any excessive forward strain on the upper along the sides of the shoe as the upper is wiped upwardly and inwardly over the curved surface of the last at the shank portion by the shank lasting devices 268, the grippers 231 which engage the upper not far from the ball line at opposite sides of the shoe are moved inwardly toward the shoe in response to inward movement of the shank lasting devices. As shown, particularly in Figs. 1 and 3, the handles 488 of the grippers 231 are provided with laterally extending arms 526 arranged to be engaged by pins 528 projecting from the carriers 282 of the opposite shank lasting mechanisms. It will be evident that as the carriers 282 move toward the .shoe the pins 528 will engage the arms 526 and move the grippers 231 against the tension of the springs 418 toward the shoe to carry those portions of the upper just forwardly of the shank lasting devices inwardly as the upper is wiped inwardly by the shank lasting devices.

The holddown 352 is arranged to lower the shoe to the proper level for the operation of the wipers, at which time the stop cam 55 arrives in position to stop the operation of the machine, as hereinbefore explained. For supporting the shoe against the thrust of the wipers in the overwiping operation there is provided a member 538 which is moved yieldingly toward the shoe and locked in engagement with the heel end thereof before the holddown 352 has completed its downward movement. The member 538 is removably secured t0 the forward end of a slide 532 which is mounted in ways formed in the top of the frame 22 for movements toward and from the shoe (Figs. 1, 3 and 4) The slide 532 is provided with depending lugs 534 for pivotally supporting a block 538 through which extends a rod 538 pivotally connected to the upper end of one arm 548 of a lever 542 fast to a shaft 544 mounted in the frame 22.. Surrounding the rod 538 between the block 533 and a nut and washer 546 on the end of the rod is a compression spring 548. The lever 542 has a laterally extending arm 558 to which there is adjustably secured a link 552', the lower end of which is pivotally connected at 554 (Fig. 10) to a lever 555 journaled on the shaft 98 and carrying at its outer end a roll 558 arranged to engage a path cam 568 formed in one side of the cam wheel 384 on the shaft 28, the construction being such that at a predetermined time in the cycle of the shaft 28, and preferably during the last portion of the downward movement of the holddown 352, the lever 582 is swung in a counter clockwise direction to move the member 538 through the spring 548 into supporting relation to the heel end of the shoe. The member 538', as shown particularly in Fig. 3, is provided with diverging arms which may be faced with leather or other suitable material andwhich are arranged to engage the opposite sides of the heel end of the shoe.

In order that the member 538 may be moved into engagement with the heel end of the shoe without tending to displace it laterally, it is adjustably secured to the forward end of the slide 532 which, for this purpose, is provided with a T-shaped slot 582 to receive the similarly shaped head of a bolt 538 which extends upwardly through the member 538 and has on its upper end a nut and washer 565 for clamping the member 538 to the slide in adjusted position. Corrugations on the underside of the member 538 and upon the upper surface of the slide assist in holding the member 538 and the slide 532 against relative movement in directions lengthwise of the shoe.

For locking the member 538 in engagement with the heel end of the shoe there are provided ratchet plates 514 secured to the frame 22, the teeth of which are arranged to be engaged by pawls 558 fast on a short shaft 518 fulcrumed on the slide 532. Fast to the median portion of the shaft 518 is a block 518 from which projects a pin 518, and connected to the pin is one end of a spring 588 the other end of which is connected to a pin 582 in the slide 532. Threaded into the underside of the block 515 is a short eye bolt 584 which is connected by a short link 585 to a member 588 slidably mounted in a bore in the block 536. The rod 538 which extends through the block 536 is provided with .a shoulder 588 which, when the parts are in' their idle positions, is arranged to engage the end of the member. 588 and thus to hold the pawls 558 against the tension of the spring 588 out of engagement with the ratchet teeth 512. As the lever 542 is'swung in a counterclockwise direction, as viewed in Fig. 1, the spring 548 acts on the block 535 to move the slide 532 toward the shoe until the. member 538 engages the heel end of the shoe. As the lever 548 continues to swing in the same direction the spring 548 yields and the shoulder 598 releases the member 588, thereby permitting the spring 588 to swing the pawls 588 toward the fixed ratchet plates 514. The pawls 538 are so disposed that at least one of them will be effective to lock the member 538 against rearward movement from shoe-supporting position.

In the operation of the machine, briefly summarized, the operator first moves the shank lasting devices 268 away from each other a distance suflicient to permit an assembled shoe to be mounted on the toe and heel rests I44, M8 with the toe end of the shoe in engagement with the toe band, 248, which determines the lengthwise position of the shoe in the machine, after which the opposite shank lasting devices are released to permit the shank lasting members 210 to engage the opposite sides of the shoe. The operator then inserts the margin of the upper around the toe end at opposite sides of the forepart within the gripper jaws 392, 396 of the toe and side grippers 236, 231, and swings the handles 408 downwardly to close the gripper jaws on the upper and by means of the handle 358 swings the holddown 352 in position over the shoe bottom. Thereafter the machine is started by depression of the treadle I06 whereupon the holddown 352 moves downwardly to depress the shoe and the toe band 249 is closed about the toe end of the shoe by the forward movement of the slide E32. As the shoe is depressed the upper is pulled lengthwise of the last and drawn tightly over the forepart by the grippers 236, 237 and .is up-wiped around the toe end by the toe band 240 and along the opposite sides of the last by the shank wipers 278, the inward movement of the wipers 219 over the rounded lateral faces of the last being imparted to the grippers 237 by engagement of the pins 528 with the arms 526 (Fig. 3). Substantially at the end of the downward movement of the holddown to depress the shoe the heel end supporting member sea is moved into supporting relation to the heel end of the shoe, after which the machine is stopped by the action of the cam 66 on the lever 14.

Before the machine is stopped by the action of the cam 65 on the lever 74 the cam 256 acts to impart to-the lever 2438 a swinging movement in a clockwise direction (Fig. 1) of sufficient extent to cause the wipers 238 to be advanced and partially closed to the edge of the shoe bottom, as illustrated in Fig. 17, thus clamping the upper against the edge of the insole. It will be understood that the downward movement of the holddown 352 to lower the shoe to the proper level for the operation of the wipers has been completed before the cam 255 thus acts on the lever 25$. It will be understood also that the initial tension of the springs 3I8 is comparatively light so that as the shank lasting devices 26!] complete their movements inwardly over the curved lateral faces of the last to press the upper against the opposite sides of the insole (Fig. 14) the friction of the devices on the upper is sufficient to prevent them from moving farther inwardly over the insole at this time.

After the machine has been brought to a stop the operator swings the handles 4G8 upwardly to open the grippers 286, 231, and release the margin of the upper. With a pair of hand pincers the operator may then make any necessary adjustment of the upper on the last after which cement may be applied to the margins of the shoe upper material, if it has not been previously applied, whereupon the machine is again started by depression of the treadle we. The cam 25% then imparts to the lever 248 a further swinging movement in the same direction to complete the advancing and closing movements of the wipers 238. Substantially at the same time the cam 3M acts to swing the lever 335 in the direction further to compress the springs 3 l8 and thereby to force the shank lasting wipers 219 inwardiy over the shoe bottom to lay the margin of the upper against the insole. As the wipers 238 begin their advancing and closing movements over the edge of the shoe bottom from the position shown in Fig. 17, the cam 382 acts to move the holddown 352 upwardly away from the shoe bottom to permit upward pressure to be applied to the shoe through the comparatively stiff compression springs I60, I 69, as hereinbefore described. At the same time the cam 566 swings the lever 414 in a clockwise direction to move the plate 432 relatively to the carrier 242 to operate the toe band 240 to release the shoe upper to prevent any reverse wiping action onthe upper as the shoe is moved upwardly by the springs use, H69.

When the wipers have reached the limit of their closing movement the stop cam 68 arrives in position to stop the operation of the machine. The machine is stopped at this point in its cycle with the margin of the upper from the heel breast line on one side of the shoe around the toeend to'the heel breast line at the opposite side of the shoe upheld with compacting pressure against the shank lasting wipers 210 and the forepart wipers "238 by the springs I60, I69, to permit the cement which has been previously applied to set sufficiently to retain the upper in lasted position. After the cement has set sufficiently to hold the upper in lasted position the machine is again started by the depression of the treadle. The cam 2 I 2 is so formed that as the machine is again started the springs I60, I69 are permitted to expand fully to relieve the pressure of the shoe on the wipers, after which the sleeve H2 is unlocked from the rod I 10 to permit the spring E82 again to become operative to uphold the rests M4, M6. After the sleeve I12 is unlocked from the rod I10 the cam 256 swings the lever 248 in a counterclockwise direction to move the carrier 242 to the left (Fig. 1) to open the wipers. 'As the wipers are swung away from each other laterally of the shoe the cam 382 (Fig. 10) acts through the bell-crank lever 33'! and links 372 to lower the holddown 352 into position to engage the bottom of the shoe and to depress the shoe relatively to the wipers before the wipers are moved outwardly over the edge of the shoe bottom. Substantially at the same time upward movement is imparted to the lever 55% (Fig. 10) by the cam 56!) to swing the lever 542 in a clockwise direction. As the lever M2 is swung in a clockwise direction the shoulder 59!] on the rod 538 (Fig. 4) engages the forward end of the memher 588 and moves it relatively to the block 536 to swing the pawls 568 out of engagement with the ratchet teeth 512 to unlock the heel end supporting member 539 after which, as the lever 542 continues to swing, the shoulder 59B engages the block 536 and moves the member 530 into inoperative or idle position. As the shoe supporting member is moved rearwardly the cam 382 swings the bell-crank lever 33'! in a direction to move the holddown 352 upwardly out of engagement with the shoe bottom, after which the stop cam It swings the lever 14 in a direction to move the clutch member into engagement with the brake surface 38 to stop the operation of the machine. The operator then grasps the handle 358 and swings the holddown 352 to the right. He then moves the shank lasting devices 250 away from each other, after which the shoe may be removed from the machine.
